His mother states that the family does not have health insurance, so they did not take him to the hospital last week when he started vomiting and had copious amounts of diarrhea. She reports that he has not had anything to eat or drink since then. The patient has snoring respirations that are rapid and inadequate. His radial pulse cannot be located, and his carotid pulse is rapid and weak. His capillary refill is 5 seconds and his skin is cool to the touch. What would your first intervention in caring for this child be?

A) Take manual spine motion restriction of the head and neck
B) Open the airway using the head-tilt, chin-lift maneuver
C) Provide positive pressure ventilation
D) Attach the automated external defibrillator
